A very pleasant walk
There are few walls as well-preserved as those in Lucca, which are about 5 miles long. They walls remain intact because, even though they were designed to defend against enemies, they were never used in battle. They encircle and mark off the historic center of the city and have been transformed into a public promenade that can be traveled in its entirety either by foot or on bike. It is a very pleasant walk, especially at sunset.
